I'm the co-author and project lead of SSH-Stamp:
https://github.com/brainstorm/ssh-stamp
Our focus has been on the "network side" by running a SSH server instead of a Web Server and multiplexing protocols via SSH sessions.
Our project is admittedly not as mature as the ESP32 Bit Pirate but OTOH we run with Rust Embedded and support other targets than Espressif (currently experimental on RPI Pico2 and Sipeed BL616).
We need testers :D
It supports sniffing, sending, scripting, and interacting with various digital protocols (I2C, UART, 1-Wire, SPI, etc.) via a serial terminal or web-based CLI. It also communicates with radio protocols like Bluetooth, Wi-Fi, Sub-GHz and RFID.
Turn a $5 ESP32-S3 into a browser-based hardware workbench.The Bit Pirate firmware is complemented by scripting, hardware dock, extension, adapters, browser tools, documentation and practical embedded workflows to enable comprehensive hardware debugging and development with serial interfaces or Wi-Fi connectivity.
Anyway, I find the tiny C3 to be much more stable than other versions. It is a bit sad the very few projects support it.
I have been getting into this as well. I had ChatGPT plan up a new UART adapter and similar.
I think I'll keep just making up basic sketches when I need to work with one of these protocols - it's also nice that if I do that, when I see it work, I know I can expand functionality from there into what I need.
